Abstract
The invention relates to a special sleeve for a double-head threaded joint of an aluminum plate finned oil cooler, which comprises a sleeve body, wherein internal screw threads matched with the threaded joint of the oil cooler are arranged in the lower end of the sleeve body, the sleeve also comprises a locking device, a steel ball and a turntable, the steel ball is placed on the turntable, the locking device passes through the turntable, and the turntable and the steel ball arranged on the turntable are fixed on the inner end surface of the sleeve body by the locking device. The special sleeve has the characteristics that the structure is simple, the operation is simple and convenient, the performance is reliable, and the like, the requirement of screwing a double-head screw bolt can be met, the steel ball can also be prevented from falling off, a double-head screw stud can be effectively prevent from retreating from a base body along a screw sleeve, and the assembly success ratio of the double-head screw stud is ensured.
Description
Technical field
The present invention relates to a kind of aluminum plate fin type oil cooler joint assembly tool, relate in particular to a kind of Special sleeve for double-head threaded joint of aluminum plate finned oil cooler.
Background technology
At present, aluminum plate finned oil cooler adopts the steel joint to replace original structure oil cooler aluminium joint mostly, has significantly improved the intensity of joint, thoroughly solved can not extensive use because of the aluminium joint intensity difference a difficult problem.But the aluminum plate finned oil cooler of new construction runs into a difficult problem when producing in enormous quantities, it is exactly the assembly problem of double thread steel joint, very easily locking when the regular screw threads sleeve uses, can't effectively the steel joint be assemblied on the aluminium oil cooler body, and in a single day kill, the steel joint also is difficult to dismounting, only has the inadequate dismounting of the steel of destruction joint ability, this has brought great difficulty for the new product volume production, in the urgent need to a kind of double thread socket wrench specially adapted for it that can prevent locking.
Summary of the invention
The present invention for overcome the above problems provide a kind of easy to use, prevent locking, improve assembly yield, the Special sleeve for double-head threaded joint of aluminum plate finned oil cooler of efficiency of assembling.
Technical scheme of the present invention is: comprise sleeve body, be provided with the internal thread suitable with the oil cooler nipple in the sleeve body lower end, described sleeve also comprises locking device, steel ball, rotating disk, described steel ball is placed on the rotating disk, and described locking device passes rotating disk and the steel ball on rotating disk and the rotating disk is fixed on the sleeve body inner face.
Described sleeve also comprises positioning sleeve, and described positioning sleeve vertically is enclosed within outside the locking device, and the upper surface of positioning sleeve contacts with the sleeve body inner face, the lower surface contacts with the lower end surface of locking device.
Described disk upper surface is provided with groove, and described steel ball is placed in the groove.
Described locking device is lock-screw.
Described sleeve body upper end is provided with the hole that is connected with spanner.
The present invention has simple in structure, easy and simple to handle, the characteristics such as dependable performance, can not only satisfy the requirement that screws stud, can also prevent that steel ball from coming off, can prevent effectively that studs from withdrawing from from matrix with swivel nut, ensured the success rate of studs assembling, thoroughly solved this bottleneck problem of double thread steel joint assembling difficulty, greatly improved efficiency of assembling, sleeve body and rotating disk all adopt mould steel to make and process is quenched, temper, make it have high hardness, intensity, wearability, enough toughness, the effectively service life of lengthening sleeve are also arranged simultaneously.
